Description

Chlorarachnion (clore-a-rack-knee-on) reptans, an unusual autotrophic amoeboid organism. The plastids were obtained by endosymbiosis from an alga, and a residual algal nucleus, referred to as a nucleomorph, provides genetic information for plastid activity. Cells often form extensive arrays with interconnected pseudopodia. The plastids are emphasised in this image. Differential interference microscopy.
